TECHNICAL FIELD

[0001] The present invention relates to natural invigorating, teaproducts and a method for preparing the same. More particularly, thepresent invention relates to invigorative teas made of certain parasiticplants, alder and/or schizandra and a method for preparing the same.

PRIOR ART

[0002] Human beings are mentally and physically affected by variousexternal and internal factors. Those factors are, weather, biosocialenvironments and nutritional conditions. Occasionally, the effect isexerted as a stress on the human body. Stress is said to be a stimulusor succession of stimuli of such magnitude as to tend to disrupt thehomeostasis of the organism. In these days of multifunctionalinformation-oriented society, human beings undergo various stresses,caused by physical, chemical and biological or emotional stimuli. Recentreports have revealed that men who are under severe or extensive stressbecome poor in virility due to reduction in their sperm concentrationand sperm motility.

[0003] Generally, sperm motility is taken as an indicator for spermviability (Noran et al., 1998), while semen motility is evaluated interms of sperm concentration, percentage of morphologically abnormalsperms, ratio of living to dead sperm, semen volume, pH, initialvitality of sperms, and mass movement of sperms (Berndtson and Pickett,1980).

[0004] After making an examination of sperm conditions of 50 persons intheir twenties (24 years old on the average) and 44 persons aged 37-53(42 years old on the average), who lived near Tokyo, Japan, the MedicalCollege of Tokyo University, Japan, made a research report whichcontained a surprising result that the men in their forties had about 84million sperm cells per ml on the average while the men in theirtwenties had a sperm count of as low as 46 millions, which is only 55%of the 40-49 age group's average. Also, it is found in the researchreport that all of the men aged around forty were capable of procreationby the criteria reported by WHO in 1992 that the minimum sperm count forconception through ordinary sexual intercourse must amount to 20 millionper ml, whereas only 86% of the men in their twenties satisfied thiscriteria. Similar sperm motilities were detected in the men in theirtwenties and forties: 27% and 28%, respectively. However, spermsproduced by the men in their twenties were measured to have a normalmorphological ratio of 52%, which was lower than that of the men intheir forties, measured to be 64%.

[0005] Also, the research report disclosed that the average sperm countof the men in their twenties and thirties had sharply reduced incomparison to that of men of the same ages 20 years ago, which werereported to have an average sperm count of 75 to 100 million in asimilar research, adding that Japanese men had also suffered from theworldwide sperm count reduction phenomenon and that endocrinedisruptors, called environmental hormones, had been deduced to play animportant role in the sperm count reduction.

[0006] Indeed, it has been known that the average sperm count from humanmales is 60% lower compared with 50 years ago. According to the reportmade by Dr Scott at the Copenhagen University Hospital in 1990, in astudy for 14,000 men, it was found that the average sperm count wasreduced to 66 million/ml with an average semen volume of 2.7 ml,representing a sharp reduction from the values of 110 million/ml and 3.9ml respectively in 1940. This sperm count reduction phenomenon was alsoconfirmed by Dr. Auger, in France. He said that average sperm counts haddropped to sixty million in 1992 from eighty nine millions in 1973 witha reduction rate of 2.1% per year.

[0007] If the sperm counts of men continue to drop at this rate, mankindwill face a sterility crisis, threatening its continued existence,within 60 years.

[0008] Having been regarded as a symbol of masculinity, being vigorousor having stamina is helpful in maintaining men's health, as well as intheir having sexual intercourse for preservation of the species or forpleasure.

[0009] Amid the current deluge of processed foods seasoned withchemicals, especially precooked foods, people tend to avoid naturalfoods. However, it is well known that one of the methods to retain thespirit and energy received from the natural system is to maintain aregimen of eating natural foods.

[0010] Artificially synthesized chemicals for use in industry andagriculture have long been known to have an abnormal influence on theworkings of the endocrine systems of human beings and animals. Indeed,animals which are problematic in development, behavior or genitalmorphology owing to endocrine disruption, are now frequently found. Thismatter of grave concern is highly apt to happen to human beings. Thechemicals are generically called endocrine disruptors, more well knownas environmental hormones.

[0011] On the other hand, with an increase in interest about sex, somepeople seek to enhance their sexual potency by means of drugs or thelike. In response to this tendency, a number of drugs are nowcommercially available. For example, medications have been developed totreat erectile dysfunction (impotence) in men. Also, people can obtaincream formulations to enhance sensual pleasure. In addition, it issuggested that alcohol improves human sex life because of its ability torelieve the tension of the nervous system. However, such drugs have manyproblems. The medication for treating impotence may be fatal to thosewho suffer from hypertension. Cream formulations are inconvenient foruse in addition to being expensive. Alcohol users may be in danger offalling into alcoholism.

DISCLOSURE OF THE INVENTION

[0012] In order to solve the above problems, the present invention hasan object of providing invigorating tea products made of natural herbs.

[0013] It is another object of the present invention to provide foodproducts which is invigorative and inexpensive

EXAMPLE 58

[0212]Boschniakia rossica Fedtsch. and polygalae japonica herba rootswere separately washed with water, dried and cut into small pieces whilecleaned, dried schizandrae fructus and torilis fructus were crushed. 1 gof the chopped Boschniakia rossica Fedtsch., 2 g of the choppedpolygalae japonica herba roots, 5 g of the crushed schizandrae fructusand 3 g of torilis fructus were steeped in 900 ml of water at 90° C. for6 hours to give 850 ml of a natural tea of the present invention.

[0213] In the above tea examples of preparing the natural tea productsaccording to the present invention, it is noted that the sameextractant, water or ethanol, was used for the different materials ineach example as in the example 1 through 48. However, it is of coursepossible to use different extractants for the different materials orherbs adopted in the same example.

[0214] After hosts of experiments with various compositions of theparasitic plants and alder and/or schizandrae fructus, extractscomprising 20-80% by weight of the parasitic plants and correspondingly80-20% by weight of alder and/or schizandrae fructus were found to bepreferably effective in invigorating the body.

[0215] Also, a preferred invigorating effect could be obtained whenpolygalae japonica herba roots and/or torilis fructus was present at anamount of 10-70% by weight based on the total weight of the materialsused.

[0216] As described above, the herbal materials can be steeped orextracted separately or in a mixture of them with a preference to anextraction ratio of 40-120 cc/g. As for the extractants, they must beaqueous and edible like water and ethanol. The extraction period of timedepends on the concentration of ethanol in the extractant. It should beunderstood that the extraction period of time can not be a reason forlimiting the scope of the present invention.

[0217] Of the parasitic herbs, the herbal material indispensable for thepresent invention, Lathraea japonica Miq. was found to be more effectivein invigorating the body than the other two species, Orobanchecoerulescens Steph. and Boschniakia rossica Fedtsch., the former beingmore effective than the latter.

[0218] Compared with a natural tea comprising an extract from eitherpolygalae japonica herba roots or torilis fructus, a natural teacomprising extracts from both polygalae japonica herba roots and torilisfructus showed a further improved invigorating effect.

[0219] Differently from the above examples, the same materials as usedin the above-described examples may be steamed and dried so as for theresulting mixture to be soaked in boiling water to give a natural teaaccording the present invention. Preferably, the mixture isfreeze-dried. Alternatively, the mixture of the tea materials either inthe natural state or in the steamed state may be powdered to give anatural tea according to the present invention as claimed in theaccompanying claims.

[0220] As for the alder, all its parts, including fruits, sprigs, leavesand roots, were found to be effective although the fruit was notincluded in the above description and the alder extracts as described inthe claims mean all parts of alder as above.

[0221] In addition to roots of polygalae japonica herba, its leaves andstems are useful in the present invention. Even in the case of torilisfructus, its roots as well as fruits were found to be effective ininvigorating the body.

[0222] In order to improve the taste or flavor of the natural teaaccording to the present invention, additives such as sweeteners andflavorings may be added to it.

CONTROL EXAMPLE

[0223]Boschniakia rossica Fedtsch. was cleaned and chopped to pieces,after which 4 g of the chopped Boschniakia rossica Fedtsch. was steepedin a mixture of 250 ml of 95% ethanol and 160 ml of water at 60° C. for6 hours to give 150 g of an extract.

Experimental Test

[0224] An experimental test was carried out to confirm the invigoratingeffect of the natural tea products of the present invention. Each of 87men in their forties to seventies was allowed to drink 140 ml of anatural tea of this invention twice a day, after breakfast and justbefore sleeping for 30 days and then effects of the teas on the sex lifethe subjects were measured. For comparison, the tea prepared in ControlExample was used as a control. The results are given in Table 1, below.TABLE 1 Natural Men's Age Tea Effectivness 40-49 50-59 60-69 70-79Control Effective 0 0 Ineffective 6 6 Example 1 Effective 6 Ineffective1 Example 10 Effective 6 Ineffective 2 Example 29 Effective 7Ineffective 1 Example 37 Effective 6 6 Ineffective 1 1 Example 57Effective 5 5 5 Ineffective 0 1 1 Example 58 Effective 5 5 4 4Ineffective 0 1 1 1 Total Effective 35 16 9 4 Ineffective 5 3 2 1

[0225] As apparent from Table 1, the natural tea products preparedaccording to the present invention are effective in invigorating thebody although the effect is dependent on subjects' physical and mentalconditions, such as health, stamina and the like.
